Web Services for Core SDK

This page describes how to make api calls from SDK.

This section provides a reference for the following Web Service APIs for Android Core SDK.

Prerequisite steps

Step 1: Initialise web service

Create an object of MerchantWebService with any of the supported API commands.

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey(merchantKey); // Merchant key
merchantWebService.setCommand(<Api Commands>); // Pass the command name
merchantWebService.setVar1(<Pass var 1 value>) // Pass the var1 calue
merchantWebService.setHash(<Api Command Hash>) // Pass the Hash value, and use the below formula

For more information on Web Service hash generation, refer to Generate Static Hash.

📘
Generate Hash for MerchantWebService: To generate Hash refer to Hash Generation, use the following algorithm:
sha512(key|command|var1|salt)
where
key= "Your Key"
command= <"Api Commands"> // Pass Command Name
var1= <"default"> // Pass the var1 value
salt= "Your SALT"

Step 2: Create Merchant web service PostData

PostData postData = new MerchantWebServicePostParams(merchantWebService).getMerchantWebServicePostParams();
if (postData.getCode() == PayuErrors.NO_ERROR) {
payuConfig.setData(postData.getResult());
}

📘
Troubleshoot Postdata code errors: If the PostData code snippet (above) is returning errors, check the data point set in merchantWebService.

Enable Payment Options

This API is used enable multiple payment options on your checkout page.

📘
Hash logic: The hash logic for this API is:
<key>|payment_related_details_for_mobile_sdk|<userCredential>|<salt>
For more information, refer to Generate Static Hash.

Step 1: Execute GetPaymentRelatedDetailsTask

This class is used to get payment-related details. It takes an instance of a class that implements the PaymentRelatedDetailsListener interface as input.

GetPaymentRelatedDetailsTask paymentRelatedDetailsForMobileSdkTask = new GetPaymentRelatedDetailsTask(this);

The PaymentRelatedDetailsListener interface has an abstract method called onPaymentRelatedDetailsResponse(). This method is called when the payment-related details are received.

Step 2: Get Response using onPaymentRelatedDetailsResponse()

Get response to determine the availability of various payment options (UPI, Google Pay, PhonePe, LazyPay, and Generic Intent) similar to the following code snippet:

@Override
public void onPaymentRelatedDetailsResponse(PayuResponse payuResponse) {
mPayuResponse = payuResponse;
// Check if UPI as payment option available.
if(payuResponse.isUpiAvailable()){
// To check if UPI as payment option is available
}
if(payuResponse.isGoogleTezAvailable()){
// To check if Google Pay as payment option is available
}
if(payuResponse.isPhonePeIntentAvailable()){
// To check if Phonepe as payment option is available
}
if(payuResponse.isLazyPayAvailable()){
// To check if LazyPay as payment option is available
}
if(payuResponse.isGenericIntentAvailable()){
// To check if Generic Intent as payment option is available
}
//For SI Payments
if(payuResponse.isNBAvailableFoSI){
//Fetch SI NB List from payuResponse.getSiBankList() method
}
}

This method is called when the payment-related details are received. This method takes a PayuResponse object as input. The PayuResponse object contains the payment-related details.

The onPaymentRelatedDetailsResponse() method can be used to check if the following payment options are available:

UPI
Google Pay
PhonePe Intent
LazyPay
Generic Intent
The onPaymentRelatedDetailsResponse() method can also be used to fetch the list of SI banks if SI payments are enabled.

Get Checkout Details API

The Get Check Out Details API provides information on the bank down status, tax info, and offers enabled on a merchant key. You can call this API is similar to other Web Services. The only difference is that it requires a JSON in var1 as in the following code block:

{
   "requestId":"1614595430980",
   "transactionDetails":{
      "amount":5000
   },
    "customerDetails": {
      // optional
      "mobile": "9999999999" // optional
    },
   "useCase":{
      "getAdditionalCharges":true,
      "getTaxSpecification":true,
      "checkDownStatus":true,
      "getExtendedPaymentDetails":true,
      "getOfferDetails":true
   }
}

Where the requestId is a unique random number passed in the request.

Step 1: Create the var1

Mobile SDK has a Utility class to create a JSON, as explained above. The implementation is similar to the following code snippet:

  Usecase.Builder usecase = new Usecase.Builder()
  .setCheckCustomerEligibility(true)
  .shouldCheckDownStatus(true) // set it to true to fetch bank down status for each payment option 
  .shouldGetAdditionalCharges(true) // set it to true to fetch additional charges applicable on each payment option
  .shouldGetOfferDetails(true) // set it to true to fetch offers enabled on merchant key 
  .shouldGetExtendedPaymentDetails(true) // set it to true to get extended payment details
  .shouldGetTaxSpecification(true) // set it to true to fetch tax info applicable on each payment mode 
  .build();
  
  GetTransactionDetails.Builder transactionDetails = new GetTransactionDetails.Builder()
  .setAmount(1000.0)//transaction amount in double
  .build();
  
  //Passing Customer Details is optional and can be used 
  //to check EMI eligibility based on mobile number
  CustomerDetails.Builder customerDetails = new CustomerDetails.Builder()
  .setMobile("9999999999") //pass the mobile number if want to get eligibility status in payment option
  .build();
  
  String var1 = new GetCheckoutDetailsRequest.Builder()
            .setUsecase(usecase)
            .setCustomerDetails(customerDetails)
            .setTransactionDetails(transactionDetails)
            .build().prepareJSON();

After getting var1, pass that in Merchant Web Service with the command as PayuConstants.GET_CHECKOUT_DETAILS.

Step 2: Get API response

PayuResponse is received in the onCheckoutDetailsResponse() callback method of CheckoutDetailsListener as mentioned in the API Commands Supported table.

Get additional charges, bank down status, and offers

Additional Charges are returned in the PaymentDetails object for each payment option. The following example code snippet is for fetching Additional Charges for Net Banking:

//if netbanking is available on merchant key
if(payuResponse.isNetBanksAvailable()){
ArrayList<PaymentDetails> netbanks = payuResponse.getNetbanks();
}

Additional Charge is available inside each PaymentDetails object and can be accessed using the paymentDetails.getAdditionalCharge() method
Similarly, bank health is available inside each PaymentDetails object and can be accessed using the paymentDetails.isBankDown() method.
For Offers, An ArrayList<PayuOffer> is available inside each PaymentDetails object. To get the offers list, use the paymentDetails.getOfferDetailsList().

Get tax info

Tax is not applied on individual Net Banking or card schemes but instead applied at the payment mode level for all CC(Credit Card), DC(Debit Card), NB(Net Banking), Wallets, etc. So, to fetch the Tax Specification, use the following code block:

if(payuResponse.isTaxSpecificationAvailable())
TaxSpecification taxSpecification = payuResponse.getTaxSpecification();

taxSpecification.getCcTaxValue() //tax applicable on CC transactions
taxSpecification.getDcTaxValue() //tax applicable on DC transactions
taxSpecification.getNbTaxValue() //tax applicable on NB transactions
taxSpecification.getCashTaxValue() //tax applicable on Wallet transactions
...

Lookup API

The Lookup API is used when integrating Multi-Currency Payments on Android Core SDK.

Step 1: Create request

The Lookup API needs a JSON request. Product type needs to be passed either as DCC or MCP. DCC means Direct Currency Conversion, that is, it returns the conversion prices for card currency only. To get all enabled currencies on Merchant Access Key and their conversion prices, use product type as MCP. For DCC, cardBin is mandatory, but cardBin is not required for MCP. The following example is a request for DCC as the product type:

{
   "merchantAccessKey":"E5ABOXOWAAZNXB6JEF5Z",
   "baseAmount":{
      "value":10000.00,
      "currency":"INR"
   },
   "cardBin":"513382",
   "merchantOrderId":"OBE-JU89-13151-110",
   "productType":"DCC",
   "signature":"be5a56667354d9e2ea5ea1c6af78b0afc1894eb2"
}

To create the Lookup API request as above, use the LookupApiRequestBuilder class similar to the following code block:

String postData = new LookupRequest.LookupApiRequestBuilder()
                .setAmount("10000.00")
                .setCardBin("513382")
                .setCurrency("INR")
                .setMerchantAccessKey("E5ABOXOWAAZNXB6JEF5Z")
                .setMerchantOrderId("OBE-JU89-13151-110")
                .setProductType(LookupRequest.ProductType.DCC)
                .setSignature(hash)
                .build().prepareJSON();

 val postData = LookupRequest.LookupApiRequestBuilder()
                .setAmount("10000.00")
                .setCardBin("513382")
                .setCurrency("INR")
                .setMerchantAccessKey("E5ABOXOWAAZNXB6JEF5Z")
                .setMerchantOrderId("OBE-JU89-13151-110")
                .setProductType(LookupRequest.ProductType.DCC)
                .setSignature(hash)
                .build().prepareJSON()

The following example request is for MCP as the product type.

{
   "merchantAccessKey":"E5ABOXOWAAZNXB6JEF5Z",
   "baseAmount":{
      "value":10000.00,
      "currency":"INR"
   },
   "merchantOrderId":"OBE-JU89-13151-110",
   "productType":"MCP",
   "signature":"be5a56667354d9e2ea5ea1c6af78b0afc1894eb2"
}

To create the Lookup API request for MCP, use the LookupApiRequestBuilder class similar to the following code block:

String postData = new LookupRequest.LookupApiRequestBuilder()
                .setAmount("10000.00")
                .setCurrency("INR")
                .setMerchantAccessKey("E5ABOXOWAAZNXB6JEF5Z")
                .setMerchantOrderId("OBE-JU89-13151-110")
                .setProductType(LookupRequest.ProductType.MCP)
                .setSignature(hash)
                .build().prepareJSON();

 val postData = LookupRequest.LookupApiRequestBuilder()
                .setAmount("10000.00")
                .setCurrency("INR")
                .setMerchantAccessKey("E5ABOXOWAAZNXB6JEF5Z")
                .setMerchantOrderId("OBE-JU89-13151-110")
                .setProductType(LookupRequest.ProductType.MCP)
                .setSignature(hash)
                .build().prepareJSON()

Parameter Name	Description
Amount	Transaction Amount
Card Bin	First 6 digits of card number
Currency	Base Currency of Transaction
Merchant Access Key	Merchant Access Key provided by PayU
Merchant OrderId	A unique request id for Lookup API request
Product Type	Use MCP to get all enabled currency on Merchant Access Key or DCC to get direct currency conversion for card currency
Signature	Hmac SHA1 hash created with formula explained below

To calculate signature, create the HmacSHA1 hash of the following data:

Signature =HMAC-SHA1(data, key);
Data = baseCurrency+merchantOrderId+baseAmount
Key = Secret Key shared with the merchant at the time of on-boarding
Example data,
baseCurrency = "INR"
merchantOrderId = "OBE-JU89-13151-110"
baseAmount = "10000.00"
hashString = INROBE-JU89-13151-11010000.00

Step 2: Call LookupTask

Here, this is an object of a class that implements LookupApiListener. The following is a signature of LookupApiListener:

public interface LookupApiListener {
    void onLookupApiResponse(PayuResponse payuResponse);
}

interface LookupApiListener {
    fun onLookupApiResponse(payuResponse: PayuResponse?)   
}

Step 3: Get LookUp API response

After you execute LookupTask, the onLookupApiResponse callback method is called:

@Override
public void onLookupApiResponse(PayuResponse payuResponse){    
    
    //Fetch lookup Details using below code
    LookupDetails lookupDetails = payuResponse.getLookupDetails();     
    }

override fun onLookupApiResponse(payuResponse: PayuResponse?){    
    
    //Fetch lookup Details using below code
    val lookupDetails = payuResponse.lookupDetails
    }

VAS API

The VAS API is used to get the list of down Net Banking and card BIN that is down.

📘
Note : You can check if a particular NetBanking service is down or not by just passing the bankCode or card-bin (first 6 digits of card number) and in payuResponse, the response will be fetched, for instance.

Step 1: Call ValueAddedServiceTask

Integrate this API by calling the ValueAddedServiceTask method:

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey(merchantKey);
merchantWebService.setCommand(PayuConstants.VAS_FOR_MOBILE_SDK);
merchantWebService.setVar1(PayuConstants.DEFAULT);
merchantWebService.setVar2(PayuConstants.DEFAULT);
merchantWebService.setVar3(PayuConstants.DEFAULT);
merchantWebService.setHash(<Api Command Hash>) // Pass the Hash value, and use the below formula

Step 2: Get onValueAddedServiceApiResponse

After you execute ValueAddedServiceTask, the onValueAddedServiceApiResponse callback method is called:

  @Override
    public void onValueAddedServiceApiResponse(PayuResponse payuResponse) {
        if (mPayuResponse != null) {
           // It means given NetBanking code or cardnumber is not down i.e. it is in good to go condition
            } else {
           // It means given NetBanking code or cardnumber is down and you can display the responseMessage if you want or you can customize it
            }
        }
    }

Eligible Bins for EMI API

The Eligible BINs for EMI API fetches a list of eligible Bins for EMI corresponding to each Bank name along with minimum amount. 

📘
Hash logic: The hash logic for this API is:
<key>|eligibleBinsForEMI|default|<salt>
For more information, refer to Generate Static Hash.

Step 1: Set parameters

Set the parameters similar to the following snippet:

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey(merchantKey);
merchantWebService.setCommand(PayuConstants.ELIGIBLE_BINS_FOR_EMI);
merchantWebService.setVar1("BIN"); // This parameter needs can include either Bin or NET.
merchantWebService.setVar2(cardBin); // The first 6/8/9 digits of card number or network token.
merchantWebService.setHash(<Api Command Hash>) // Pass the Hash value, and use the below formula

Step 2: Handle the response

Handle the API response for eligible bins for EMI and log the raw response for debugging or informational purposes.

@Override
 public void onEligibleBinsForEMIApiResponse(PayuResponse payuResponse) {
    Log.d(TAG, "onEligibleBinsForEMIApiResponse: " + payuResponse.getRawResponse());
}

Get EMI According to Interest API

Get EMI According to Interest API is used to get information to get details related to EMI such as EMI amount, tenure in month, interest rate, etc.

📘
Hash logic: The hash logic for this API is:
<key>|vas_for_mobile_sdk|<amount>|<salt>
For more information, refer to Generate Static Hash.

Step 1: Set parameters

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey(merchantKey);
merchantWebService.setCommand(PayuConstants.API_GET_EMI_AMOUNT_ACCORDING_INTEREST);
merchantWebService.setVar1(amount); // The amount that must be converted to EMI.
merchantWebService.setHash(<Api Command Hash>) // Pass the Hash value, and use the below formula

Step 2: Handle response

@Override
public void onGetEmiAmountAccordingToInterestApiResponse(PayuResponse payuResponse) {
    Log.d(TAG, "onGetEmiAmountAccordingToInterestApiResponse: " + payuResponse.getRawResponse());
}

Get Transaction Info API

The Get Transaction Info API is used to extract the transaction details between two given time periods.

Step 1: Set parameters

The API takes the input as two dates and the time (initial and final) between which the transaction details are needed. The output would consist of the status of the API (success or failed) and all the transaction details in an array format. Set startTime and endTime in the payment params as described in the following code block:

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey(merchantKey);
merchantWebService.setCommand(PayuConstants.GET_TRANSACTION_INFO);
merchantWebService.setVar1(startDate); // The starting Time (from when the transaction details are needed
merchantWebService.setVar2(endDate); // The end Time (till when the transaction details are needed).
merchantWebService.setHash(<Api Command Hash>) // Pass the Hash value, and use the below formula

Step 2: Handle response

@Override
public void onGetTransactionApiListener(PayuResponse payuResponse) {
    Log.d(TAG, "onGetTransactionApiListener: " + payuResponse.getRawResponse());
}

Verify Payment API

The Android SDK provides a wrapper for the Verify Payment API that allows your mobile application to reconcile transactions with PayU's database securely. This integration is essential for Android developers implementing PayU payment functionality in their apps.

Why Use Verify Payment in Your Android App

When implementing payments in your Android application, transaction responses may occasionally fail to reach your app due to network issues or user interactions (like app switching or device issues). The Verify Payment feature ensures your app can confirm transaction statuses directly with PayU's servers, preventing discrepancies in payment records.

📘
Android Developer Note:: Implementing this verification step in your Android payment flow protects your application from potential payment status tampering and ensures a reliable payment experience for your users.

Android Implementation

Step 1: Configure the Verify Payment Request

In your Android payment handling class, implement the Verify Payment API using the MerchantWebService provided by the PayU Android SDK:

// Import the required PayU Android SDK classes
import com.payu.india.Model.PayuResponse;
import com.payu.india.Payu.PayuConstants;
import com.payu.india.Payu.PayuMerchantWebService;

// In your payment verification method
private void verifyTransactionStatus(String transactionId) {
    MerchantWebService merchantWebService = new MerchantWebService();
    
    // Set your merchant credentials and API parameters
    merchantWebService.setKey(merchantKey);
    merchantWebService.setCommand(PayuConstants.VERIFY_PAYMENT);
    
    // Set the transaction ID to verify
    // For multiple transactions, use pipe symbol (|) as separator: "txnId1|txnId2|txnId3"
    merchantWebService.setVar1(transactionId);
    
    // Generate and set the hash for secure communication
    String hashString = merchantKey + "|" + PayuConstants.VERIFY_PAYMENT + "|" + transactionId + "|" + salt;
    String hash = calculateHash(hashString);
    merchantWebService.setHash(hash);
    
    // Execute the verification request
    merchantWebService.postWebServiceRequest(this);
}

Step 2: Implement the Response Handler

Add the response handler in your Activity or Fragment that implements PayuResponseListener:

@Override
public void onVerifyPaymentResponse(PayuResponse payuResponse) {
    if (payuResponse != null) {
        // Log the complete response for debugging
        Log.d(TAG, "Payment Verification Response: " + payuResponse.getRawResponse());
        
        // Process the verification result
        if (payuResponse.isResponseAvailable() && payuResponse.getResponseStatus().equals(PayuConstants.SUCCESS)) {
            // Transaction verified successfully
            // Update your app's UI or database based on the verified status
            String transactionStatus = payuResponse.getResult();
            updateTransactionStatus(transactionStatus);
        } else {
            // Verification failed - handle accordingly
            handleVerificationFailure(payuResponse.getErrorMessage());
        }
    }
}

Best Practices for Android Implementation

Always verify after receiving payment notifications - Implement the verification call in your app's payment completion handler
Handle timeouts appropriately - Set reasonable timeouts for verification requests to avoid blocking your app's UI
Implement proper error handling - Create user-friendly error messages for different verification failure scenarios
Store verification results - Cache verification results locally to reduce unnecessary API calls
Background processing - Consider using WorkManager for verification to ensure it completes even if the app is closed

Troubleshooting Android Integration

Common Issues:

Hash calculation errors: Ensure your hash generation uses the correct format and encoding
Network connectivity: Implement proper retry logic for intermittent network failures
Transaction ID format: Verify that transaction IDs are correctly formatted when sending multiple IDs

For additional support with Android SDK integration, refer to the complete PayU Android SDK documentation or contact PayU mobile developer support.

Get BIN Info API

The Get Bin Info API is used to get the following using the BIN number, that is, the first six digits of a credit card or debit card:

BIN information

Detect whether a particular BIN number is international or domestic.
Determine the card’s issuing bank, the card type brand, that is, Visa, Master, etc.,
Determine the card category, that is, credit, debit, etc.

This API is used to get the card BIN details. For this API, you need to set the following parameter in the payment params similar to the following code block:

Step 1: Create Post Request

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey(merchantKey); // Merchant key
merchantWebService.setCommand(PayuConstants.GET_BIN_INFO);
merchantWebService.setVar1("1")
merchantWebService.setVar2("1") //only for SI
merchantWebService.setVar5("<pass card BIN Number>") // Pass card BIN Number
merchantWebService.setHash(<Api Command Hash>) // Pass the Hash value, and use the below formula

Step 2: Get onBinInfoApiResponse

@Override
public void onBinInfoApiResponse(PayuResponse payuResponse) {
}

Get Card Information API

The Get Card Information (Check is Domestic) API is used to get if the card (passed in cardBin info API) is domestic or international. This API returns the following parameters:

card_type
category
issuing_bank
is_atmpin_card

For this API, you need to set the following parameter in the payment params similar to the following code block:

Step 1: Create Post Request

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey(merchantKey); // Merchant key
merchantWebService.setCommand(PayuConstants.CHECK_IS_DOMESTIC);
merchantWebService.setVar1("<pass the card Bin number>")
merchantWebService.setHash(<Api Command Hash>) // Pass the Hash value, and use the below formula

Step 2: Get onGetCardInformationResponse

@Override
public void onGetCardInformationResponse(PayuResponse payuResponse) {
   Log.d(TAG, "onGetCardInformationResponse: " + payuResponse.getRawResponse());
}

Offer APIs

The following APIs used for offers with Android Core SDK:

Fetch Offer Details
Validate Offer Details

Fetch Offer Details

Use this API to fetch the offer list available for the merchant.

To integrate this API call the fetchOfferDetails pass the requestData as parameters as shown in the code snippet below:

payuConfig = new PayuConfig();
payuConfig.setEnvironment(PayuConstants.STAGING_ENV);

V2ApiTask v2ApiTask = new V2ApiTask(merchantKey, payuConfig);
FetchOfferApiRequest fetchOfferApiRequest = new FetchOfferApiRequest.Builder().setAmount(100.00).setUserToken("56789067890").build();
v2ApiTask.getOffers(fetchOfferApiRequest, new HashGenerationListener() {
    @Override
    public void generateSignature(HashMap<String, String> hashMap, HashCompletionListener hashCompletionListener) {
        String hashName = hashMap.get(PayuConstants.CP_HASH_NAME);
        String hashData = hashMap.get(PayuConstants.CP_HASH_STRING);
        Log.d(TAG, "generateSignature: " + hashName);
        Log.d(TAG, "generateSignature: " + hashData);
        String hash = HashGenerationUtils.generateHashFromSDK(hashData, salt);
        HashMap hashMap1 = new HashMap();
        hashMap1.put(hashName, hash);
        hashCompletionListener.onSignatureGenerated(hashMap1);  // If you are passing wrong Hash then you will get null response
    }
}, new FetchOfferDetailsListener() {
    @Override
    public void onFetchOfferDetailsResponse(PayuResponse payuResponse) {
        Log.d(TAG, "onFetchOfferDetailsResponse: " + payuResponse.getRawResponse());
    }
});

Validate Offer API

Use this API to validate the offer for the merchants.

To integrate this API call the method  validateOfferDetails and pass the requestData as parameters as shown in the code snippet below:

List<String> offerKey = new ArrayList<>();
offerKey.add("<pass the offer key>");

PaymentDetailsForOffer paymentDetailsForOffer = new PaymentDetailsForOffer.Builder().setPaymentCode("CC").setCardNumber("5123456789012346").setCategory("CREDITCARD").build();

Check Balance API

The Check Balance API can be used to fetch detail of the Sodexo card with the source ID.

Step 1: Set parameters

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey(merchantKey);
merchantWebService.setCommand(PayuConstants.CHECK_BALANCE);
merchantWebService.setVar1(sodexoSourceId); // This parameter must contain the Sodexo Source ID
merchantWebService.setHash(HashGenerationUtils.generateHashFromSDK(hashData, salt));

Step 2: Handle response

@Override
  public void onCheckBalanceResponse(PayuResponse payuResponse) {
    Log.d(TAG, "onCheckBalanceResponse: " + payuResponse.getRawResponse());
}

Tokenized Payment APIs

You can store and get stored card details from the vault. The tokenized payments for Android Core SDK includes the following APIs:

Get Tokenized Stored Cards API
Get Tokenized Stored Card Details API
Delete Tokenized Stored Cards API

Get Tokenized Stored Cards API

The Get Tokenized Stored Cards API is helpful in getting all the stored cards for a particular user. For this API, you need to set theuserCredentials in the payment params similar to the following:

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey("<pass the merchant key>");
merchantWebService.setCommand(PayuConstants.GET_TOKENISED_USER_CARD);
merchantWebService.setVar1(user_credentials); //In var1, pass the user_credential
merchantWebService.setHash("<pass the hash value>");

To integrate this API call the getTokenizedStoredCards method similar to the following:

@Override
public void onGetTokenisedCardResponse(PayuResponse payuResponse) {
        
}

Get Tokenized Stored Card Details API

The Get Tokenized Stored Card Details API is used to get details of the stored card to make payment on another PG.

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey("<pass the merchant key>");
merchantWebService.setCommand(PayuConstants.GET_TOKENISED_CARD_DETAILS); 
merchantWebService.setVar1("<user_credentials>"); //In var1, pass the user_credential
merchantWebService.setVar2("<cardToken>"); //In var2, pass the cardToken to get the saved card details
merchantWebService.setHash("<pass the hash value>");

@Override
public void onTokenisedCardDetailsResponse(PayuResponse payuResponse) {
        
}

Delete Tokenized Stored Cards API

The Delete Tokenized Stored Cards API is helpful in deleting stored cards.

MerchantWebService merchantWebService = new MerchantWebService();
merchantWebService.setKey("<pass the merchant key>");
merchantWebService.setCommand(PayuConstants.DELETE_TOKENISED_USER_CARD);
merchantWebService.setVar1("<user_credentials>"); //In var1, pass the user_credential
merchantWebService.setVar2("<cardToken>"); //In var2, pass the cardToken to delete the saved card details
merchantWebService.setHash("<pass the hash value>");

To integrate this API call the deleteTokenizedStoredCard method similar to the following:

@Override
public void onDeleteTokenisedCardResponse(PayuResponse payuResponse) {

}
